AURA public engineering cases

Inputs, outputs and limits—not unsupported marketing claims.

These records show how AURA moves from a defined engineering question to a controlled calculation, configuration or evidence result. Each case separates what is demonstrated from what still requires detailed analysis, manufacturing evidence or test.

Calculation and synthesis cases

Solved inverse case · screening only

80 N radial + 360 N axial → three opposed-conical candidates

A locked 30 mm shaft interface, 4,032 searched combinations, 399 feasible states and three published trade-offs for margin, compactness and supply pressure.

Controlled direct case · bearing to rotor

AURA-PS-J15-20K: defined journal support → coefficient matrix → rotor decision

R = 15 mm, L = 30 mm, C = 30 µm, ps = 6 bar and 20,000 rpm. The same controlled support state appears across the product, spindle application and rotor-decision sequence.

Physical and validation evidence

Peer-reviewed hardware track

Adjustable-conical aerostatic spindle architecture

Analytical model, rotor-stability criterion and full-scale experiment published in the International Journal of Manufacturing Research. Reported case improvements include −11% mass, −17.3% overall dimensions and −25% air consumption.

Open validation registry

Method-chain and dual benchmark-family anchors

The conical anchor records residuals of 3.938%, 7.143% and 7.692%. The journal L4 anchor closes 4/4 holdout rows with a 10.282% maximum residual and a passing leakage audit.

Commercial use: a public case proves a workflow and a bounded result; it does not prove fit for a different machine. A client pilot begins with the actual speed, loads, shaft envelope, supply basis and decision question.

Bring one engineering decision.

Non-confidential values are enough for the first fit check. If the case is suitable, the written scope defines required inputs, outputs, exclusions, schedule and decision authority before work begins.
